[This review was collected as part of a promotion.] I have used the "entry level" (inexpensive ones) 3M filters in the past and didn't have a problem with them. So I thought I would splurge and get the one that lasts for 3 months instead of the monthly ones that I have used. This did not disappoint, the quality is superior in comparison to the competition that is out there. Plus easier to change every quarter than monthly.

[This review was collected as part of a promotion.] the 3M - Filtrete™ Ultra Allergen Bacteria and Virus 1600 MPR 1603-4PK, 20 in x 25 in x 1 in (50.8 cm x 63.5 cm x 2.5 cm) fit perfectly into my system and It is of high quality in terms of sturdiness. It will filter out levels of allergens and bacteria that my old filter wasn't able to handle

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.

[This review was collected as part of a promotion.] I have tried many cheaper brand filters and you get what you pay for. These Filtrete™ Ultra Allergen Bacteria and Virus are worth every dollar you spend on them. These trap so much more dust than any other filter out there. Stick with the best quality when you care about your air quality.

[This review was collected as part of a promotion.] I got this for our little rental house and it was exactly what we needed. The fit is perfect and the installation was a breeze. I use 3M a lot and knew the quality would be fantastic, so when it came to replacing the filter, there was no doubt I would get 3M. Highly recommend!
